SIGNAL-LANTERN.

SPECIFICATION forming part of Letters Patent No. 633,079, dated September 12, 1899.

Application filed June 28, 1899. Serial No. 722,152. (No modehl The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation'of the improvementwith parts in position for dis-' playing the danger-signal. Fig. 2 is a side elevation of thered or danger globe. is a sectional side elevation of the same. Fig. 4 is an inverted plan View of the same, and Fig. 5 is asectional plan View of part of the base of the lantern.

The improved lantern is provided with a suitably-constructed base A, a fount B, and

a burner O, inclosed within the usual fixed white globe D, having a suitable guard E for protecting the same. A second globe F, of a color in contradistinction to the color of the globe D, is arranged within the latter. and is adapted to be put inposition on the burner B, so that a danger-signal is displayed when the globe-F is in an active position, as shown in Fig. 1. The globe F is provided with a base F, supporting rods F for holding the cylindrical globe in position on the base, said globe being made of mica, glass, or other suitable material and of a red or like color. The

globe proper, F, is preferably cylindrical in shape, as is plainly illustrated in the drawings, and the base F is in the form of an inverted frustumof a cone, and on the lower edge of the base is pivoted a hinge, as at G, carrying an apertured bottom F made ring- I Fig. 3.

shaped, and prongs F project from the inner edge of the bottom and are alternately bent upward and downward, as is plainly indicated in Figs. 1, 2, 3, and 4. The upwardly-extending prongs F engage the upper portion B ofthe fountB,the downwardly-extending prongs resting on a bead B and on said fount, so that the bottom is held in a fixed position relatively to the fount and the vburner. On the hinge or pivot Gis arranged a spring H, pressing against the baseF, so as to hold the globe keyhole-opening A inthe top of the base A and carrying at its lower end a ring J, adapted to be engaged by the operator. Now when the operator exerts a pull on the ring J then a swingingmotion is given to the globe F to swing it to one side of the burner between the latter and one side of the fixed globe D, as indicated in dottedlines in Fig. 1, the axis of the globe F now standing approximately at right angles to the vertical axis of the lantern.' The raysot' light from the burnerO now readily pass sidewise through the open ends of the globe F, so that no red light is reflected from the lantern, the, latter to all practical purposes displaying a white or safety light only. It isunderstood that when the globe F is swung into the sidewise position described against the tension of the spring H it is necessary to lock the globe in. this position, and for this purpose the operator passes the registering link of the chain J intothe small portion of the opening A, so that the chain is locked against upward movement, and consequently holds theglobe F in a sidewiserposition. When it is again desired to use the lantern for displaying a red or danger signal, the operator unlocks the chain at the opening A in the base A and allows the spring H to swing the globeF-into a concentric position relatively to the globe D and the burner, sothat now a red or danger light'is displayed by the lantern. 7

From the foregoing itis evident that the device is very simple and durablein construction and can be readily manipulated by the operator to move the globe either i nto an active or inactive position, as described, for the lantern to display a red or danger signal or a white or safety signal. Furthermore, only one signal-lantern is required for white and red lights, and the expensive red globe now used on danger-signal lanterns is completely dispensed with.

Having, thus fully described myinvention, I claim as new and desire to secure by Letters Patent 1. A lantern, comprising a burner and two globes of different colors, one of the globes being fixed relatively to the burner, and the other globe being movable to allow of bringingitinto an active position around the burner movable globe being then at right angles to the vertical axis of the lantern, substantially as shown and described.

3. An attachment for ordinary lanterns, comprising a red globe, a bottom on which the globe is hinged, and arranged for attachment to the burner or fount of the lantern, a spring pressing said globe, to normally hold the latter in a closed position relatively to the bottom, and a chain connected to said globe, for imparting a swinging movement thereto, substantially as shown and described.

4. A lantern comprising a burner and two globes of diiferent colors, one of the globes being fixed relatively to the burner and the other globe being movable, to allow of bringin g it into an active position around the burner forthe lantern to display a danger-signal, or into an inactive position between the burner and one side of the fixed globe for the lantern to display a safety-signal, means-for retaining said movable globe in an active position, and means fol-swinging it into an inactive position and looking it in place therein, as set forth.
